I've build successfully 21.0 "Uzbek Black" and now tried to build
"Benadir" but got a segmentation fault. The only difference in setup
between the two builds is a newer version of egcs (currently: gcc
version egcs-2.91.51 19980714).
I'm running Linux 2.1.108 and use a glibc 2.1 snapshot on i486.
Now I'm trying to build a minimal xemacs that has debugging/error
checking enabled with gcc 2.7.2.3. I'll tell the results.
